Determine the volume at the equivalence point if a 0.100 M NaOH(aq) solution is used to titrate the following acidic solutions: (a) 30.0 mL of 0.600 M HClO4(aq) (b) 50.0 mL of 0.400 M HI(aq)

For a: The volume of NaOH used in the titration is 180 mL

For b: The volume of NaOH used in the titration is 200 mL

Explanation:

To calculate the volume of base, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid

are the n-factor, molarity and volume of base

We are given:

Putting values in above equation, we get:

Hence, the volume of NaOH used in the titration is 180 mL

We are given:

Putting values in above equation, we get:

Hence, the volume of NaOH used in the titration is 200 mL
